How do you promote coloring in pomegranates? Please keep these practical tips
Pomegranates are tender and juicy with a unique flavor, and they have certain medicinal and health value, making them deeply loved by consumers. The color of their peel is one of the important qualities of the fruit. Red-skinned pomegranates have a huge market in China because of their good appearance and auspicious meaning. So are there any methods to promote pomegranate coloring? Let's learn about them together with the editor.
I. Coloring methods
1. Coloring time
If the pomegranates have been bagged, then the bags must be removed in time for coloring from late August to early September. Generally, the bags are removed about 20-25 days before harvest.
2. Leaf removal and fruit turning
This method is an auxiliary method to promote full coloring of pomegranate fruit. Pomegranate leaf removal is done in two rounds. The first is carried out in early to mid-June together with fruit thinning and fruit setting, removing the small leaves at the base of the fruit stem and the leaves covering the fruit surface. This can both reduce the harm of pests and diseases to the fruit and make bagging easier. The second leaf removal is carried out 15-20 days before the fruit colors in mid to late August. At this time, remove or thin out the leaves or branch groups that block direct sunlight on the fruit surface, so as to achieve the purpose of fruit coloring.
3. Laying reflective film
This method is to lay silver reflective film under the pomegranate canopy or between plants and rows from mid-August to before harvest, which can significantly improve the color of fruits in the inner canopy and middle and lower parts that do not get enough light. After laying the film, branches should be properly thinned and bent so that light spots are evenly distributed on the ground under the canopy.
4. Spraying foliar fertilizer
This method is to spray pomegranate leaves with low-concentration potassium dihydrogen phosphate or potassium sulfate, plant ash extract, and other micro-fertilizers every 10 days in early August. This can promote pomegranate fruit coloring, improve fruit quality, and reduce fruit cracking before harvest.
II. Precautions
When removing bags from pomegranates, pay attention to climate changes and to fruit peel sunburn caused by high temperatures and strong sunlight exposure, which lowers fruit quality. Also, water must be strictly controlled 10-15 days before pomegranate harvest, especially in dry mountainous and hilly orchards and in plain orchards with irregular irrigation. After a long drought followed by rain, harvest in time.
